Generic requirements and framework for Pseudo Wire Emulation Edge-to- Edge (PWE3) have been described in [PWE3-REQ] and [PWE3-FW]. This draft provides encapsulation formats and semantics for connecting SONET/SDH edge networks through a packet network using IP or MPLS. This basic application of SONET/SDH interworking will allow service providers to take advantage of new technologies in the core in order to provide traditional SONET/SDH services.
